TheSerialPort.forget() method of theSerialPort interface returns aPromise that resolves when access to the serial port is revoked.

Description

A website can clean up permissions to access a serial port it is no longer interested in retaining by callingSerialPort.forget(). Calling this "forgets" the device, resetting any previously-set permissions so the calling site can no longer communicate with the port.

For example, for an educational web application used on a shared computer with many devices, a large number of accumulated user-generated permissions creates a poor user experience.
